fbdev: add mutex for fb_mmap locking
In which a mutex was added when changing smem_start and smem_len fields,
so the mutex inside the fb_mmap() call is actually used.
The problem was that set_fb_fix, which modifies the above 2 fields,
was called before and after registering the framebuffer,
which when used before registration, lead to a failed attempt to
use an uninitialized mutex.
Solution: Don't use mutex before framebuffer registration.

Commit

removed the wrong ifdef:
# define cpu_is_omap730() 1

Instead of removing removing the #endif at the end of the file,
the #endif before #else should have been removed.
But we cannot have multiple #else statements as pointed out by
Alistair Buxton <a.j.buxton@gmail.com>. So the fix is to:
- remove the non-multi-omap special handling, as we need to
detect between omap730 and omap850 anyways.
- add the missing #endif back to the end of the file

DPLL5 programming should be taken care of by the clock framework.
The driver should not need to worry about programming this

Also, the DPLL5 m and n values used were valid only for a

The problem was that set_fb_fix, which modifies the above 2 fields,

which when used before registration, lead to a failed attempt to
use an uninitialized mutex.

pty: reconnect the BSD TIOCSPTLCK handling to legacy ptys
David Howells noticed (due to the compiler warning about an unused
'pty_ops_bsd' variable) that we haven't actually been using the code
that implements TIOCSPTLCK for legacy pty handling. It's been that way
since 2.6.26, commit
3e8e88ca053150efdbecb45d8f481cf560ec808d to be
exact ("pty: prepare for tty->ops changes").
DavidH initially submitted a patch just removing the dead code entirely,
and since nobody has apparently ever complained, I'm not entirely sure
that wouldn't be the right thing to do. But since the whole and only
point of the legacy pty code is to be compatible with legacy distros
that don't use the new unix98 pty model, let's just wire it up again.
And clean it up a bit while we're at it.

PM / yenta: Fix cardbus suspend/resume regression
Since 2.6.29 the PCI PM core have been restoring the standard
configuration registers of PCI devices in the early phase of
resume. In particular, PCI devices without drivers have been handled
this way since commit
355a72d75b3b4f4877db4c9070c798238028ecb5
(PCI: Rework default handling of suspend and resume). Unfortunately,
this leads to post-resume problems with CardBus devices which cannot
be accessed in the early phase of resume, because the sockets they
are on have not been woken up yet at that point.
To solve this problem, move the yenta socket resume to the early
phase of resume and, analogously, move the suspend of it to the late
phase of suspend. Additionally, remove some unnecessary PCI code
from the yenta socket's resume routine.
Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13092, which is a
post-2.6.28 regression.

wext: add back wireless/ dir in sysfs for cfg80211 interfaces
The move away from having drivers assign wireless handlers,
in favour of making cfg80211 assign them, broke the sysfs
registration (the wireless/ dir went missing) because the
handlers are now assigned only after registration, which is
too late.
Fix this by special-casing cfg80211-based devices, all
of which are required to have an ieee80211_ptr, in the
sysfs code, and also using get_wireless_stats() to have
the same values reported as in procfs.

iwlwifi: fix debugfs buffer handling
We keep track of where to write into a buffer by keeping a count of how
much has been written so far. When writing to the buffer we thus take the
buffer pointer and adding the count of what has been written so far.
Keeping track of what has been written so far is done by incrementing
this number every time something is written to the buffer with how much has
been written at that time.
Currently this number is incremented incorrectly when using the
"hex_dump_to_buffer" call to add data to the buffer. Fix this by only
adding what has been added to the buffer in that call instead of what has
been added since beginning of buffer.
